Abstract

L'invention concerne un procédé pour attaquer une source de lumière, ledit procédé comprenant les étapes suivantes : a. fourniture d'un code devant être envoyé par la source de lumière ; b. conversion du code en une séquence de différents niveaux de courant, lesquels niveaux de courant sont maintenus pendant une période de temps prédéterminée ; et c. fourniture de la séquence de différents niveaux de courant à la source de lumière de manière que la source de lumière émette de la lumière à différents niveaux d'intensité, l'attaque de la source de lumière étant réalisée en utilisant une fréquence de mise à jour de point de consigne ayant une période de mise à jour de point de consigne, caractérisé en ce que les transitions entre les différents niveaux de courant durent plus d'une période de mise à jour de point de consigne.
